Oil Pressure Transducer


UPC9 sputtered thin- film oil pressure transducer is manufactured based on sputtering technics. The pressure medium can act on 17-4PH stainless steel diaphragm directly. The transducer's "micro" level resistance film is made by means of molecular bonding, then to be made to the needed Wheatstone bridge by microelectronics technology , and to form a metal- type sensing elements without using any adhesives. Therefore the transducer has no any moving parts, also do not need sealed chamber and oil-filled cavity. 

UPC9 oil pressure transducer is featured with good long-term stability for working is harsh environments.

UPC9 oil pressure transducer is a high-performance product and designed for oil well logging, well testing and pressure gauge application especially. It can work stably under high temperature, and have good ability on anti-vibration, impact resistance, moisture-proof.
